There are three main reasons for the noise when the wiper scrapes the windshield: 1. Wiper blade aging or foreign objects on the windshield: This is the most common cause of noise when the wiper scrapes the windshield. Wiper blades are made of rubber, and prolonged exposure to outdoor conditions such as wind, rain, and sunlight can easily cause them to age. Aged wiper blades will not clean the windshield properly and may leave streaks of water marks. In this case, replacing the wiper blades is the solution. 2. The wiper blade is too soft or improperly adjusted, causing it to hit the A-pillar: Many car owners choose to purchase and replace wiper blades themselves. Many aftermarket wiper blades available online may fit in size but differ in material hardness compared to original equipment manufacturer (OEM) parts. This can cause the wiper blade to hit the A-pillar during operation, especially with beam-style wipers. 3. Noise from the wiper motor and linkage mechanism: Many mechanics emphasize that you must spray water before using the wipers. Besides helping to clean dust more effectively, this also reduces the friction resistance of the wiper blade on the windshield. Prolonged dry wiping can place a heavy load on the wiper motor and linkage mechanism, leading to motor damage or loosening of the linkage mechanism, resulting in noise.

I just came back from a long drive, and the noise from the wipers gave me a headache. It might be due to aging wiper blades—the rubber strips harden over time and squeak against the glass. Another reason could be dirt buildup on the windshield, like oil film or dust, causing friction noise. Dry weather with less moisture makes the wipers more prone to squeaking when dry-wiping. Loose installation can also lead to rattling sounds. Experience tells me that safe driving comes first—the noise isn’t just annoying but also affects visibility, especially during heavy rain, increasing the risk of accidents. I’ve developed a habit of spraying some wiper fluid and wiping the windshield with a towel before driving. If I notice anything unusual, I check or replace the blades immediately. I recommend changing the blades every six months—it’s cost-effective and hassle-free.

Every time I encounter this situation while driving, my first thought is to check the wiper blade condition—aged rubber tends to squeak; dirty glass is also common, like when there's bird droppings or dust accumulated on the windshield that hasn't been wiped. Installation issues can also arise, such as loose arm clips that need to be re-fastened; extreme heat or cold making materials brittle can also increase friction noise. It's recommended not to wait until heavy rain to act urgently—regularly clean the glass with dish soap and water during normal times; when replacing wipers, choose ones that fit your car model, and it only takes five minutes to do it yourself; always keep wiper fluid handy to maintain moisture and prevent issues, as prevention is key to safety.

Finding the wiper making noise, possible reasons include worn or aged wiper blades causing dry scraping; accumulated dirt on the glass such as oil film or insect remains; unstable arm installation leading to shaking sounds; dry environment increasing friction. After driving for a long time, I've developed a habit of immediately cleaning the glass and wiping the wiper head clean to try. If it doesn't work, I replace the blades to ensure safety.

Upon hearing the noise, I suspect it's due to worn-out wiper blades; excessive dirt on the glass like wax residue; loose fasteners during installation; or insufficient water in dry weather. Here's how to fix it: thoroughly clean the glass with warm soapy water and rinse it dry; check the elasticity of the wiper blades—replace them if hardened and snap them tightly onto the arm; apply some specialized lubricant to reduce friction noise, which works well; and perform monthly inspections to prevent malfunctions.

Recalling my driving experience, the most common cause of wiper noise is aged blades where the rubber hardens; oil or dust on the windshield can also cause friction; not to mention improper installation or dry weather adding to the trouble. The noise isn't just annoying—it's a major hazard, as poor visibility in rainy conditions can easily lead to accidents. I take immediate action: try cleaning the glass with a white vinegar solution, and if that doesn't work, replace the wiper blades without hesitation; choose high-quality products and ensure they're properly installed and securely fastened; make it a habit to inspect them quarterly; safe driving starts with attention to detail.
